Project mention: Ask HN: Did you encounter any Leap Year bugs today? How bad was it? | news.ycombinator.com | 2024-02-29Billing. It always has to be the billing. For a list of all other edge cases, you have: https://github.com/kdeldycke/awesome-falsehood#readme
Then make a form and use PHPMailer.
Project mention: Caniemail.com (like caniuse but for email content) | news.ycombinator.com | 2024-05-06What an excellent resource! (And yes Outlook is a pain!)
We've tried building email templates for notifications for our apps where I work, and it has typically been a pain. We have since swapped to using mjml (https://mjml.io/) to build the templates, and it's working wonders. The output seems the be the most compatible with all different devices that we've tested on.
The other tool we enjoy using is Litmus (litmus.com), which allows you to throw in an email template and see what it looks like on all kinds of apps and devices.
Both of these have been really invaluable to designing emails for our apps.
The Nodemailer module is used to connect to the SMTP server through the nodemailer.createTransport function, then the email is sent with transporter.sendMail. At the beginning of the function, each parameter of the mail is verified. If something is missing, the status code 405 is returned.
I fully agree, moreover this:
> Rolling release distributions like OpenSUSE Tumbleweed follow upstream much more closely while still maintaining stability through thorough automated testing
Shows the author hasn't used Tumbleweed for any reasonable amount of time himself[0][1][2]. I daily drove it for a short while before moving to Fedora.

Ah the famous [email protected] email addresses we used to use in our test scripts to avoid sending email to anyone by accident. If we need to test the contents of the email then we use Mailhog these days. Can’t recommend it enough.

Project mention: Launching Osint Industries: Discover Your Digital Footprint in Realtime | news.ycombinator.com | 2023-08-09Greetings, HN community. We are excited to share OSINT Industries, a platform dedicated to real-time open-source intelligence (OSINT) pertaining to phone numbers and emails.
About OSINT Industries:
Realtime Analysis: We provide an up-to-the-moment enrichment tool for emails, and phone numbers.
Real-Time Intelligence: We refrain from using databases. Every piece of data is fetched in real-time, ensuring its accuracy and timeliness. None of the queries or results are stored.
Extensive Reach: Our tool can identify associated accounts linked to a particular email or phone number from over 200 websites.
Detailed Insights: Beyond basic association, our system can pull additional data points, such as images, map locations, and more.
Pedigree: Our foundation is built upon proven tools our team made in the past like Holehe (https://github.com/megadose/holehe), GHunt (https://github.com/mxrch/GHunt), and onionsearch (https://github.com/megadose/OnionSearch).
User Base: Within 3 months of our inception, we've got over 350k registered users.
Trust & Reliability: Our tool has been integrated by various global law enforcement agencies, showcasing its reliability and utility.
Try the tool for free to discover the digital footprint of your email and phone number. The first 5 searches are free: https://osint.industries
We offer API access to enterprises, if you're interested in that contact me on [email protected].
As our tool deals with data that some may view as sensitive, I think it is also important to link our policies here which govern our ethics, and data processing.

Project mention: Preview emails with letter_opener, MailCatcher and MailHog | news.ycombinator.com | 2023-08-13hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).
MailCatcher (https://github.com/sj26/mailcatcher) and MailHog (https://github.com/mailhog/MailHog) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.
Happy to answer any question! thanks, harrison
Third, Send-MailMessage has been deprecated. Try MailKit instead. To be honest, though, I'm yet to find time and test it myself.
